Quote: 'Rebels withdrew from al-Shaar under heavy bombardment by pro-government forces to the Marjeh and Maadi neighborhoods, local media activist Mahmoud Raslan told The Associated Press. Several gunmen were killed. “Morale has hit rock bottom,” he said from inside the city’s remaining rebel-held enclave.'

Al Qaida and related extreme groups, and IS, never mention morale hitting rock bottom. Just silence from them is the norm.

This quote tells me that the ones now being bombed and shelled out of Aleppo are ordinary anti-government fighters who look to help from the outside world, but being less religiously extreme, they become demoralized when, as usual, it fails to materialize in the way they still hope for and expect.
